Configuring Security
The absence of security on the Guest AP is designed to make it as easy as possible
for guests to get a connection without having to program any security settings in their
clients.
For a minimum level of protection on a guest network, you can choose to suppress
(prohibit) the broadcast of the SSID (network name) to discourage client stations from
automatically discovering your access point. (See also "Does Prohibiting the Broadcast
SSID Enhance Security?" in this manual). For more about the Guest network, see
"Setting up Guest Access" in this manual.
Static WEP
Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless
networks. All wireless stations and access points on the network are configured with a
static 64-bit (40-bit secret key + 24-bit initialization vector (IV)) or 128-bit (104-bit secret
key + 24-bit IV) Shared Key for data encryption.
You cannot mix 64-bit and 128-bit WEP keys between the access point and its client
stations. Static WEP is not the most secure mode available, but it offers more protection
than plaintext mode as it does prevent an outsider from easily sniffing out unencrypted
wireless traffic. (For more secure modes, see the sections on "IEEE 802.1x," "WPA
with RADIUS," or "WPA-PSK" in this manual. WEP encrypts data moving across the
wireless network based on a static key. (The encryption algorithm is a "stream" cipher
called RC4.)
The access point uses a key to transmit data to the client stations. Each client station
must use that same key to decrypt data it receives from the access point.
Client stations can use different keys to transmit data to the access point. (Or they can
all use the same key, but this is less secure because it means one station can decrypt
the data being sent by another.)
If you selected "Static WEP" Security Mode, provide the following on the access point
settings:
